JA Daily Science Report for Expedition 308, 07 June 2005 


LOCATION: Site U1319 


SCIENCE UPDATE: The lithologies recovered at Hole U1319A included mainly hemipelagic clays (ranging from greenish gray to brown), with minor intercalations of fine sand and silt. Frequent cm-scale sandy layers in core U1319A-2H (between 4.5 and 14 mbsf) were interpreted as a series of distal turbidites, and a 2 cm thick white ash layer was recovered at 22.7 mbsf in core U1319A-3H, section 6. This ash layer could provide a useful regional stratigraphic marker. The T2P probe was deployed in the hole for the first time, but due to the fact that the formation was stiffer than anticipated, the tip of the probe was bent and the data may not be reliable. Since all scientific objectives for the site were fulfilled, a decision was made to stop coring operations when the last seismic unit was penetrated (at 150 mbsf). As of 2400, core U1319A-5H was being described and the vessel was steaming to the location of Site U1320.
